[Simple-support] Using DefaultType=PROPERTY by default

[Roman P. <rom...@gm...>]

Hello.

By default, simplexml uses fields to map object data to/from XML. This
can be overriden by using @Default(DefaultType.PROPERTY) on each
class.
In our project, we need to use the property-centric approach, and it's
a bit uncomfortable to annotate every single model class, as this is
error-prone: someone can forget to annotate some class, a
field-centric strategy will be used, so some getter/setter logic will
not be called leading to tricky errors.
simplexml actually contains a 'meta-default': in
org.simpleframework.xml.core.Support class, DefaultType.FIELD is
hard-coded as a default for cases when no @Default annotation is
specified (an 'override'). Support class is instantiated by Persister,
so it seems to be pretty straight-forward to add a parameter (or other
way to configure it) defining such a default to the Persister, which
would in turn pass this setting via constructor to Support.
My question is - is this plausible? Doesn't it break some big architecture rule?
I can craft a patch implementing this approach.
